Scheduled US IMAP email server downtime

On 26 August 2026 at between 11:00 am and 4:00 pm US/Pacific time our network team will be performing infrastructure maintenance. During this 5-hour window, network connectivity to one of our US IMAP/POP3 email servers will be interrupted for up to 1 hour.

As a result, some customer mailboxes will be unavailable for up to 1 hour during the network interruption. Customers who will be impacted by the interruption have been emailed directly.

No incoming mail will be lost during the interruption. Mail that arrives during the interruption will be deferred and delivered once connectivity to the mail server is restored.

Email forwarding and SMTP services will not be affected, however messages sent via SMTP during the interruption will not be stored as sent mail in IMAP folders on the server.

We'll update our status page at http://status.opalstack.com/ at the beginning of the maintenance window. To be informed of system status updates automatically please subscribe at https://status.opalstack.com/subscribe.

If you have any questions or concerns regarding this maintenance then please contact the Opalstack support team.

Past Incidents

19th September 2024

Web: Phoenix MariaDB down on opal7

The MariaDB service on opal7.opalstack.com (Phoenix AZ shared hosting) is currently down. We're attempting to restore service and will follow up as soon as possible.

  • The recovery and repair is complete and the MariaDB service is operating normally.

  • The cause of the MariaDB outage was corruption in the service's InnoDB store.

    The service is now operational while running recovery and repair routines in the background. We expect the recovery and repair to take several hours but the service should remain operational in the interim.

  • The MariaDB service is back online at this time but service may be intermittent as we continue to troubleshoot.

    • Web: Frankfurt opal6 under heavy load

    opal6.opalstack.com (Fraankfurt shared hosting) is currently under heavy load and is responding very slowly. We're attempting to identify and correct the cause at this time and will follow up when more info is available.

  • The server is back online following the reboot. The cause was a runaway Apache httpd process consuming all of the server's available RAM.

    We'll identify the site that caused the problem and will work with the site owner to prevent the problem from occurring again.

  • We're unable to troubleshoot due to the extremely high load, so we are rebooting the server at this time.

    Web: Washington D.C. Intermittent network connectivity to opal12

    At this time network connectivity to opal12.opalstack.com is intermittent and customer sites may be inaccessible. We're investigating at this time and will update when more information is available.

  • We've seen no further issues.

  • We've identified and blocked an abusive IP address that was saturating the network. Connectivity is stable at this time. We will continue to monitor.

  • Connectivity is failing again, we'll continue to troubleshoot.

  • opal12 is back online at this time. We suspect that a network issue upstream in the data center was the cause. We're awaiting confirmation and will continue to monitor.

    Web: Washington D.C. opal12 blocked by Malwarebytes

    At this time opal12.opalstack.com (Washington DC shared hosting) is being blocked by Malwarebytes. The cause was an outbound SSH attack from a compromised customer shell account which caused the server to be listed in a major block list. As a result visitors who use Malwarebytes may see a warning when visiting sites hosted on opal12.

    We're working with the block list operator to have the server delisted and expect to have this resolved within the next couple of days.

    In the meantime, you may be able to work around the problem by adding your site domain and/or server IP 207.244.121.250 to your Malwarebytes exception list.

  • opal12.opalstack.com is no longer blocked by Malwarebytes.
